IMPORTANT SAFETY INSTRUCTIONS FOR HEAT GUNS READ THESE INSTRUCTIONS
Hidden areas such as behind walls, ceilings, floors, soffit boards and other panels may contain flammable materials that could be ig-nited by the heat gun when working in these locations. The ignition of these materials may not be readily apparent and could result in property damage and injury to persons. When working in these locations, keep the heat gun moving in a back-and-forth motion. Lingering or pausing in one spot could ignite the panel or the material behind it.

Extreme care should be taken when stripping
paint. The peelings, residue and vapors of paint may contain lead, which is poisonous. Any pre-1977 paint may contain lead and paint applied to homes prior to 1950 is likely to contain lead. Once deposited on surfaces, hand to mouth contact can result in the in-gestion of lead. Exposure to even low levels of lead can cause irreversible brain and ner-vous system damage; young and unborn chil-dren are particularly vulnerable.
Before beginning any paint removal process you should determine whether the paint you are removing contains lead. This can be done by your local health department or by a pro-fessional who uses a paint analyzer to check the lead content of the paint to be removed.

LEAD-BASED PAINT SHOULD ONLY BE RE-MOVED BY A PROFESSIONAL AND SHOULD NOT BE REMOVED USING A HEAT GUN.

Persons removing paint should follow these guidelines:

1. Keep the work area well ventilated. Open the windows and put an exhaust fan in one of them. Be sure the fan is moving the air from inside to outside.

2. Remove or cover any carpets, rugs, furniture, clothing, cooking utensils and air ducts.

3. Place drop cloths in the work area to catch any paint chips or peelings. Wear protective clothing such as extra work shirts, overalls and hats.

4. Work in one room at a time. Furnishings should be removed or placed in the center of the room and covered. Work areas should be sealed off from the rest of the dwelling by sealing doorways with drop cloths.

5. Children, pregnant or potentially pregnant women and nursing mothers should not be present in the work area until the work is done and all cleanup is complete.

6. Wear a dust respirator mask or a dual filter (dust and fume) respirator mask which has been approved by the Occu-pational Safety and Health Administra-tion (OSHA), the National Institute of Safety and Health (NIOSH), or the United States Bureau of Mines. These masks and replaceable filters are readily available at major hardware stores. Be sure the mask fits. Beards and facial hair may keep masks from sealing properly. Change filters often. DISPOSABLE PAPER MASKS ARE NOT ADEQUATE.

7. Use caution when operating the heat gun. Keep the heat gun moving as excessive heat will generate fumes, which can be inhaled by the operator.

8. Keep food and drink out of the work area. Wash hands, arms and face and rinse mouth before eating or drinking. Do not smoke or chew gum or tobacco in the work area.

9. Clean up all removed paint and dust by wet mopping the floors. Use a wet cloth to clean all walls, sills and any other surface where paint or dust is clinging. DO NOT SWEEP, DRY DUST OR VACUUM.
   Use a high phosphate detergent or trisodium phosphate (TSP) to wash and mop areas.

10. At the end of each work session put the paint chips and debris in a double plastic bag, close it with tape or twist ties and dispose of properly.

11. Remove protective clothing and work shoes in the work area to avoid carrying dust into the rest of the dwelling. Wash work clothes separately. Wipe shoes off with a wet rag that is then washed with the work clothes. Wash hair and body thoroughly with soap and water.

Additional Safety Warnings

• Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gasoline, carbon tetra-chloride, ammonia, etc. may damage plastic parts.
• Ensure the switch is in the off position be-fore inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.
• Do not use as a hairdryer or direct the hot air blast at other people. The high temperature being produced may cause personal in-jury.
• Do not direct airflow directly on glass. Extreme temperature changes may cause the glass to break resulting in personal injury or property damage.
• Do not leave the tool unattended while it is switched on.
• Allow the tool to cool fully before storing. Contact with tool while still hot may cause personal injury and/or property damage.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, de-pending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Attaching and Removing Nozzles
All nozzles that are available accessories from Bosch are compatible with Bosch heat guns.
To attach the nozzle accessory, such as the reflector nozzle (Fig. 1, 11) or the reduction nozzle (10), insert between the nozzle (1) and removable heat shield (2). Push gently to insert.
To remove, allow the nozzle to cool down to room temperature, and pull accessory gently from the nozzle.

Operation

Initial Use
A coating applied at the factory protects metal surfaces from corrosion. This protective coating will burn off during initial use and smoke may be observed. The heat gun may also display discolorations on the nozzle caused by the normal operating temperatures. This does not indicate damage and the function of the tool is not affected.

Selecting Power Setting
The output level setting (Fig. 1, 3) has two different output temperature levels, 570 °F and 930 °F (300 °C and 500 °C). The LED work light (6) flashes briefly to indicate that the temperature setting change is made.
To select 570 °F push the output level setting (3) down, toward the bottom of the tool. To select 930 °F, push the output level setting (3) up.

Switching On/Off
To switch the tool on, first press the lock-off button (Fig. 1, 4) and then the on/off trigger (5). After the tool has been turned on, you can release the lock-off button (4).
To switch the tool off, release the on/off trig-ger switch (5).

Restart Protection
If the battery pack (Fig. 1, 9) is removed from the heat gun while in operation, the restart protection is activated and the LED work light (6) flashes until the on/off switch (5) is released. To resume operation, first ensure a battery pack has been inserted. Next, turn the tool off and then back on by releasing and then pressing the on/off trigger switch (5).

Overheat Protection for the Battery Pack
If the battery pack (Fig. 1, 9) gets excessively hot during operation, the output is reduced. The LED flashes slowly for as long as the on/ off trigger switch (5) is pressed. If the heat gun continues to be operated and the temperature in the battery pack increases further, the heat gun will switch off.

Reduced Output
Battery packs rated 4.0 Ah and above are recommended to achieve the maximum airflow and temperature levels listed in the Specifications section. Activating the heat gun with a battery pack rated less than 4.0 Ah will cause the LED work light (Fig. 1, 6) to flash slowly several times. This indicates the heat gun is operating with reduced output.

Built-in Work Light
Upon starting the heat gun, the LED work light (Fig. 1, 6) switches on and illuminates the work area.
The LED work light (6) is also used as a status indicator. The status indications are list-ed in the table below.

Overheat Protection for the battery pack
Flashing rapidly while the on/off switch is pressed| Internal error Service required

Operating Tips
To maintain the desired heating and prevent possible damage, do not position the nozzle (1) too close to the workpiece. Positioning the nozzle too close to the workpiece could result in air blockage and can lead to the over heating of the heat gun.

Applications

• Warning: Read all safety warnings, instructions, illustrations and specifications provided with this heat gun. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
• Warning: To reduce the risk of fire, property damage, or personal injury, place a protective shield between the heating area and adjacent surfaces. Pro-tect yourself and others from hot paint trimmings and gas or dust.
• Warning: Move the work piece outdoors. If this is not possible, keep the work area well ventilated. Open the windows and put an exhaust fan in one of them. Be sure the fan is moving the air from inside to outside.
• Caution: To reduce the risk of injury, do not remove or attach accessory tips until tool has cooled to room temperature.

Removing Paint & Adhesives
Warning: Extreme care should be taken when stripping paint. The peelings, residue and vapors of paint may contain lead, which is poisonous. Any pre-1977 paint may contain lead and paint applied to homes prior to 1950 is likely to contain lead. Once deposited on surfaces, hand to mouth contact can result in the in-gestion of lead. Exposure to even low levels of lead can cause irreversible brain and nervous system damage; young and unborn children are particularly vulnerable.

1. Briefly soften the paint or adhesive with hot air. Move the heat gun slowly and constantly from side to side to evenly distribute heat. Many adhesives can be softened by using heat. Long heat exposure burns the paint or adhesive and makes removal more difficult.
2. Remove paint or adhesive with a clean spatula.

Soft Soldering

1. Attach the reduction nozzle (Fig. 3, 10).
2. If you are using solder without flux, apply soldering grease or paste to the solder joint.
3. Heat the solder joint.
4. Apply the solder. The solder must be melted by the temperature of the work-piece.
5. If necessary, remove the flux after the sol-der joint has cooled down to room temperature.

Applications
Heat Shrinking

1. Attach the reflector nozzle (Fig. 4, 11).
